Should I Believe The Backup Failed?

In the documentation it says you can use the “ALL_NONUSB” variable or token to specify which drives you want UrBackup to image or maybe I’m reading that wrong.

Under Settings » Volumes to backup I have entered “ALL_NONUSB” (without the quotes)

I want the main internal drive fully imaged.

So, fast-forward 4 hours later …

One of my backup logs said this …

UrBackup just did a full image backup of "Profound IT Services, LLC, Desktop (Dell), Nicolae (DESKTOP-6SPED2)".

( 2 infos, 0 warnings, 3 errors)

2023-10-18 19:27:46(info): Starting scheduled full image backup of volume "ALL_NONUSB"...
2023-10-18 19:27:46(error): Could not read MBR. Error message: CreateFile of volume 'ALL_NONUSB:' failed. - sendMBR. Errorcode: 2
2023-10-18 19:27:46(error): Cannot retrieve master boot record (MBR) for the disk from the client.
2023-10-18 19:27:46(info): Time taken for backing up client Profound IT Services, LLC, Desktop (Dell), Nicolae (DESKTOP-6SPED2): 0ms
2023-10-18 19:27:46(error): Backup failed

I think the system is expecting a letter like “x:” not a variable.

Should it be something like “%ALL_NONUSB%”?

Should I trust that the backup is still fine. Both partition seem to be on the backup server as images. What would you do here? I need to clarify this situation.
